The average lifespan of a squirrel in Alberta varies depending on the species.

The 2 main species found in Alberta are the Red Squirrels and the Eastern Gray Squirrels.

It also depends on their environment and interactions with humans.

Lifespans of Alberta Squirrels:

In the Wild

Red squirrels live 5-8 years on average, while the Eastern gray squirrel has a lifespan of 6-12 years on average.

In Captivity

Both the Red Squirrel and the Eastern Gray Squirrels can live up to 20 years in captivity.

This makes perfect sense as you remove predation and starvation from the mix when in captivity.

Types of Squirrels in Alberta

Red Squirrels

Native to Alberta, red squirrels are small-sized rodents that generally live 5-8 years. Their population is stable and they are widely distributed throughout the province.

Eastern Gray Squirrels

Originally from the eastern parts of North America, the Eastern gray squirrel has been introduced to Alberta. In the wild, their lifespan ranges from 6-12 years.

Factors Affecting Lifespan

Predation

The main predators of squirrels in Alberta include birds of prey, coyotes, and domestic animals like cats and dogs. Predation significantly affects the overall lifespan.

Food Availability

Squirrels in Alberta primarily feed on nuts, seeds, and berries. Access to a steady food supply can increase their lifespan.

Human Impact

Urbanization and road accidents can also affect the lifespan of squirrels in Alberta. Areas with high human activity generally result in lower life expectancies for squirrels.

Lifespan in Captivity vs Wild

Squirrels in captivity often have a longer lifespan compared to those in the wild. In a controlled environment, free from predators and with a consistent food supply, they can live up to 20 years.

Health Conditions

In captivity, squirrels are more likely to receive medical attention, further contributing to their extended lifespan.

However, they may also face stress and lack of exercise, which can negatively impact their health.
